- is to provide such needles withmeans to detect the abnormal positionof warp threads said means being actuated by such warp threads, and inconjunction with weft stop devices, operate to stop the loom.

A further object of my invention is to provide-such needles with meansto engage with and disengageirom needle operating mech' anism, saidmeans being engaged with such operating mechanism when the-needle restsin the line of travel of the said operating mechanism, and afurther-object is to pro vide the needle with means to resist acci'--dental misplacement when being carried out of the line of travel of theoperatingmechanism.- l attain this object by mechanism shown in theaccompanying drawings, in which,

Figure 1 is a view in side elevation, broken to save space, and brokenout to ,show de' tails of construction, of a weft inserting. Fig. 2,1s.

needle embodying my invention. a plan view of the parts shown in Fig. 1.Fig. 3 is a view in vertical cross section on the line 33 of Fig. 1,looking in the direction. of the arrows, this view showing a convenientand preferred cross sectional construction of a nee le. f

The needle is-indicated by letter A. l or the purpose of securingrigidity and lightness the needle in cross section has the form of aGreek cross, although other cross sectional forms, which will serve toattain the desired lightness and rigidity, may be employed. The butt endof the needle is provided with a pin, 0, which is designed to be engagedby a picker, or other mechanism, to

insert, and withdraw the needle 'from "the when not in active contactwith t e actuatmg mechanism, Near the forward or pointserves to keep theneedle from accidental mis lfacement,

end of the needle a vertical mortise'd is out, and there. isprovidedalso a thread tie-- livering eye, 0, which passes through the needle,from front to back .and intersects the aforesaid vertical mortise. ()n apin f at the end of the mortise farthest from the thread delivering eyeis pivoted a detector 9, moving in a vertical plane. The free end ofthis detector crosses the line of travel of the weft thread in itsmovement through the delivering eye, and such free end is pro its outerside and projects slightly above the lines of the needle. A spring asecured in the mortise, d, engages and holds the de tector in itselevated position, and normally preventsthe detector from interferingwith the passage of the weft through the delivering eye.

As is well known, upon the occurrence of a float in the warps, the warpshed is conpositioned ,w'arp threads would bear upon the exposed surfaceof the detector 9 and depress the free end of the same within themortise, so that the cuttingedge h would sever the weft, and free, itfrom its tension,

any suitable nature, would respond to the action of the slackened weft,and stop the loom, The needles, if carried in a series of boxes inlieuof shuttles, would as the shuttle box shifting mechanism shifted theboxes, be brought into the line of travel of the picker and the pin 0would be engaged slide within its box and project its end between thewarp shed; as the needle was shifted away, from contacting with thepicker, the spring 6 would hold the needle 111 an assumed positionduring the inactivity of the needle.
